What is the main purpose for using R1 and R2 doors on a regular basis?

The main purpose for using R1 and R2 doors on a regular basis primarily pertains to catering operations and the boarding of Persons with Reduced Mobility (PRM). R1 and R2 are typically located at the front of the aircraft, making them easily accessible and functional for boarding and deplaning passengers, especially those with specific needs who require additional assistance.

Catering services utilize these doors to facilitate the loading and unloading of food and beverage supplies necessary for in-flight services. This ensures that catering does not interfere with the main passenger boarding process. Additionally, the use of these doors allows for a smoother experience for PRM passengers who may require more space and assistance when boarding.

Overall, the R1 and R2 doors play a crucial role in maintaining efficient operations related to both catering and the accommodation of passengers with special requirements. This focus on accessibility and operational efficiency underscores the importance of these doors beyond merely serving as emergency exits or crew entry points.
